Serpentine spring is used for grid coupling. Grid Coupling is a advanced structural coupling of metal flexible coupling, which depend on two and a half snake spring embedded within the alveolar coupling to transfer torque.

The material of elastic components is nylon, so it has high hardness and resistance to wear and apply for the circumance with causticity.

ML plum blossom type elastic shaft coupling has the following characteristics: simple structure, smaller diameter, light weight, reducing shaking buffering, without lubricating, bearing large capacity, convenient repair and so on.

Widely used in internal combustion engine unit, frequency conversion unit, synchronous motor unit, reciprocating compressor unit, piston compressor unit.
